rustdoc: Fix inclusion of the new fonts

These fonts were moved into place by rust's makefiles, but rustdoc is widely
used outside of rustc itself. This moves the fonts into the rustdoc binary,
similarly to the other static assets, and writes them to the output location
whenever rustdoc generates documentation.

Closes #13593
Closes #13787
